在OpenShift上使用Jekyll

on technology

ssh到openshift机器上后默认执行gem install jekyll是没有权限的.

> gem install jekyll
Fetching: liquid-2.4.1.gem (100%)
Fetching: fast-stemmer-1.0.1.gem (100%)
Building native extensions.  This could take a while...

.......
.
Fetching: classifier-1.3.3.gem (100%)
Fetching: directory_watcher-1.4.1.gem (100%)
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied - /var/lib/openshift/blablablablablablabla/bin

sudo也不行

sudo gem install jekyll
bash: /usr/bin/sudo: 权限不够

我们可以通过自定义 Home 来达到安装jekyll的目的, 不介意的话写

> export HOME=~/app-root/runtime
> echo $HOME
/var/lib/openshift/blablablablablablablabla/app-root/runtime
> gem install jekyll

gem install jekyll
